rearward movements vthereof propel the sled Beit known thatlI,.DANI ELJ. SHULTZ, a citizen ofthe UnitedStates of America, r'esiding at SaltLake City,'i n Vthe county of Salt Lake' and State of Utah, haveinvented new and useful Improvements in Sled-Pro-l pellers, of-which thefollowing is a specifica- ,the rapid manipulation will'impartconsiderable velocity tothe sled. The guard 7prevents the lateraldisplacement of the ush rods 6 during the operation of the prope lers.The upper-relativewalls of therecess 9 are adapted to engage the pushrods 6 and' thus limit the 'rearward movements of the o-wer levers 5, asclearly shown .in 2 of tie drawin f EachV propeller is provided with abowe minals of which are connected respectively to the power lever andpush rod, as shown, VThese springs normally tend to maintain the spursll'in contact with the -surface'over of the power lever 5 My inventionrelates to sled propellers, andits primaryohject 'isto" ovide a deviceof 'this character which canhe easily applied to the sleds already inuse, whichis simple, durable' and eicienaand which can be manufaclturedvand sold at a comparatively-'low cost.

With the above and other objects in view, the invention consists in theconstrucion,

The movements ofthe push rods 6 by thesprings-15 are limited-by. the push rods coming in contact' with therelatively lower walls 4 it is desired to guide the sled, one ofthepropellers is held in the position shown in Fig. 2, Iand when it isdesired to retard the velocit of the sled, both of the levers are heldin sucii position.

Having fully described-and illustrated my invention, what I claim is:

A 'sled propeller comprising power lever formedwlt a recess and pivotalyconnected 'to thesled, a push rod pivotally mounted within the recess,the upper and lowerwalls of said recess bein inclined to form stops 'tobe engaged by t e' push rodand limit the movement ofsaid rod in eachdirection, and a s'prin'con'nectinr the rod and leverand teusione tonormally maintain the rod in engagement with one of said recessI walls.

' In testimony whereof I aiX my signature in presence of two witnesses.

Tlie ,power lever 5 is providedat a point adjacent the handle8 with a recess 9,. the relatively upper and lower walls of which areinclined in reverse directions, as fully shown in Fig. 2 of the'drawing.The push rod 6 is pivotally secured at one end. to the power lever 5 bymeans of apin 10, the end vof the push rod 6 being disposed withintherecess'9. The free end of the push rod 6 'Y 'provide'a'spur 11 adaptedto penetrate the snow vor-ice, and a'shoulder 12 adapted to limit thedegree of penetration of the s ur.
